LED vs. MH

I've been running 72 3w Cree LEDs over my 75 gal hey stocked with sps frags I gotta. Say I like the LEDs but wanna try t5s my growth is just not there

which don`t need to be the problem of 3watts or so - it is depending on the used nanometer and the resulting par/pur value. 3w can also have a output which is "okay" but not as good as a highpower 1w led
 
oldschool but you like to see simulations? for what? :wink: i bet i could convince you when you come here to switzerland. :crossedlips:
 
So I guess it's another one of those things where I'll just have to guess? Right now I am running a 36" Reefbrite and 4 x T-5s. I do not get much growth at all with my SPS eccept my pink birds nest. My Green slimmers are about the same size as they where 6 months ago. I'm looking for growth and health of my live stock. Keep the replies coming so I can make up my mind.......... My tank is just 18" deep..
 
I just switched from a t5 6 bulb setup to 2 radion fixtures. Not really sure if I like them. Corals are happy. But I'm not sure if I like the shadows and dark spots created with one source lights. I love my t5. And my tank wa truly bright

If you can afford radion buy radion....otherwise....yes....you have some research ahead of you. If I could foot the $700 trust me I would.
 
I'm looking for growth diff with MH compaired to LEDs. I am now running 1 36" Reefbrite with 4Xt-5s. Not too impressed with growth.
 
That makes one of us. Let's see....I had a 4 polyp frag that went to 9 in 4 days....birds nest is growing so fast I swear you can see it grow.
 
PICS PROVE! LET'S SEE EM! :kiss:

just some pictures of tanks here in switzerland, that are running swissmade leds. will do a threat in the next days about those leds.

When we start building our new livingroom tank i will proof you finally better :-)

but now discussion of better growth for T5/MH/LED - also the question is how fine the rest of the tank are. growth initiated by light will only take place when the rest is also fine, ca,mg,alk,temp.. in a good working tank corals can grow also with t5 - mostly better with good leds but... ;-)
 
those Swiss tanks are dosed with stuff from Sandoz that is why the colors are so spectacular...LOL j/k
 
thanks for the pics! nice looking tanks you guys have there!

nope - nothing. even no zeolite-******** (sorry) some just use balling/balling light and standard ca reactor.
And of course, we do have some "filters" here in switzerland, where you can control your nitrate to get best results.. ;-)
